' )NVENTOi i, P\ ETRQ LANTE DELLA ROVERE, 8T QNMSMWWL ATTORNEY siding in Bagnaia, near Viterbo, in the To all whom it mag concern:

. .Be it known that I, PmTRo LANTE DELLA ROVERE, a subject of the King of Ital rerovidqmof Rome, Italy, have invented. certain flaw and useful Improvements. in Armored lovers for the Protection of Rubber Tires,

of which the followin is a specification.

This invention re ates to an improved cover for rubber tires 'the'object of the same being to protect the air chamber from puncturing or from being in any other way damaged by stone splinters orother ,sharp objects, at the same time reventing the said air chamber, or the solid rubber tire fitted with this improved cover, from being rapidl worn out.

he armored cover forming the subject of the resent invention acts also as a nonskid ing cover and can be readily ada ted to fit tires of bicycles, automobiles an other carria es of every description, although in the fo lowin description as an example of a the practice ap lication of this invention,

will be describe a cover more particularly adapted for automobiles.

In order that the following description me. more readilybe understood reference she. I be'h'ad to the accompanying drawings, in which Figure 1 shows a view ofthe external side of 'a-wheel furnished with the armored cover according to the resent invcntion;.Fig. 2 shows a view of tlie inner side of the same wheel; Fi 3 .is'a portion of the cover un-' wound; F 1 4, 5 and-6 are, res ectively,

s sectionson ines X X, Y Y, and Z 1 of Fig. 1.

On axle -a is mounted the wheel whose spokes -b support the rim 'c of wood or of metal; to'the rim is secured in any convenient way the tire -d.- On the same axis is also keyed the chain-wheel which receives the motion from the ,motorof the automobile; this chain-wheel is not shown in the drawing.

The cover consists of a: certain number of elements e (Fig. 3); in'the drawing it is supposed that four of the said elements form the entire cover. The tire elements are referably chrome tanned calf-skin leather. ach of the .said elements is formed of a convenient number of portions (in the drawin'g six are shown) made clearly distinct by the triangular notches cut in the two ed es of each element. These notches areof elp in facilitating the fitting of the cover Specification of Letters Patent.

to the curved. surface of the tire; but they are not indispensable, either because the puckers which mi ht otherwise form in the edges owing to t eir excessive len th, do

notoccasion any inconvenience, or ecause leather, is eminently adaptable to curves, and may be suitably curved in order to adust it to the tire. As it a pears from the drawing, the central part 0- the cover rests on the tire, while the lateral parts remain" extended towards the hub of the wheel.

In the edges of the cover the holes h are provided, two in each section of an element,

and narrow strips c are ap lied against the inner contour'of the cover ig. 1) so that each comprises a whole section on an ele-y ment and a part of the lateral ones.

In the narrow strips four holes are .made' corresponding to those of the cover, for the purpose of fastening those parts by means of screw-bolts j; the number of the metallic strips is thus half that of the sections. To the said strips are fastened the spiral sprin -Iccarrying the threaded ,rods l,' t e latter are screwed inthe ring -m (Figs. 5 and 6) and are so adjusted as to render uniform the tension of the strips 'i'; they are kept in osition by means of winged nuts -n,-. n order that these nuts may not loosen, after the tension of the spiral springs has been regulated the locking rim -o 18 placed against the ring mand fastened thereto with screws p; the wings q ofthe nuts -non account of thelrlength or their eccentricity to the axis of the nut,- will prevent the rotation of this nut, because they will be stopped .by the locking ring Along the central longitudinal art of each element (Fig. 3) is laid a strengtliening zone r; this zone is secured to the band by means of rivets s set ver close together. Theserivcts have, towards t e outside of the cover, a spherical or conical head, and serve, not only to increase the adherence of the wheel to the ground, es ecially on country roads, but alsoto diminis the contact of the zone itself with the ground and thus to protout the zone itself, and prevent its wearing out quickly. The 'conica form of the heads of the rivets may be of especial use for drives over ice. 1

Upon the inner side of the wheel the same arrangementmay be adopted as has now been described for the outer. However,

when the motor mechanism, in general, and,

more especially, the position and the size of the chain-wheel do not admit of the application of the -m--with the spiral springs 'k then t e ad'usfiment of the section f- (Fig. 2) is e ect d by means of the latches t fixed by 1 'eans of screw-bolts or, rivets uin the various holes h of the cover section, which are thus united at their contiguous-edges. Each latch -tcarries a small tube 'v desi ed to receive the segirnents of the small circular bars -,abwhic extend through a convenient of sections, preferably coinciding the group-of sections which form an eleand-elegance;- the'rivets andthe sac-1,800

screw-bolts are of brass, the other metallic pieces are made of iron or. of polished or nickel plated steel. Of course other metals may also be used without departing from the I characteristics of the invention.

Claim.

An armored cover for the protection of rubber tires consisting of a succession of leather elements, each comprisi a group of sections limited by means 0 V-shaped notches made in the edges thereof, and with narrow strips connecting the sections, a lock ing ring, screw rods adjustabl; connected with said ring, springs connecting said ad justable screw rods to said strips, the cover elements bein protected by zones of leather furnished with radially therefrom.
